2011-8-25The gain of the proposed compression algorithm compared to the JPEG was 3-7% for the standard test images but 21-26% for the mammographic images due to their less textured nature The efficiency of our algorithm depends on the smallest subband of the compressed image - the smaller the subband the better the compression but it takes more time to compute it

The wide dynamic range of mammograms poses problems for displaying images on an electronic monitor and printing images through a laser printer In addition digital mammograms require a large amount of storage and network transmission bandwidth We applied contrast enhancement and data compression to the segmented images to solve these problems
